Weather Underground Launches Powder Predictor™ Tool for Winter Sports Enthusiasts on Wunderground.com

Unique Weather Tool Provides Users With a Powder Potential Index to Help Find the Best Conditions for Skiing and Snowboarding

SAN FRANCISCO, CA--(Marketwire - February 25, 2011) - Weather Underground, the world's first online weather service, announced today the availability of Powder Predictor™, a first of its kind weather tool that forecasts the powder quality of expected snowfall in the U.S. and Canada.

This revolutionary new tool pinpoints where the fluffiest powder is likely to fall over the coming 5 days. Essentially the tool projects the powder potential by calculating the inches of snowfall that would be required to produce an inch of liquid when melted. A higher index therefore means fluffier snow, as there will be less water content in each inch of snowfall. A low index predicts more slushy snow with higher water content.

The powder potential is displayed as a layer on wunderground.com's interactive ski map that also plots all major ski resorts across North America. Users can zoom in to any ski area and view which resorts are likely to provide the best powder. Users can also click on another layer that will plot the actual amount of forecasted snowfall. The map control panel includes a forecast slider to select different forecast ranges.

"At Weather Underground we continually look to develop and present specialized weather products that will positively impact our users' ability to make informed planning decisions," said Alan Steremberg, President and co-founder of Weather Underground. "We are particularly excited about Powder Predictor™ because it will provide snow fanatics with invaluable information to help them better plan and prepare for their mountain trips."

Weather Underground's meteorologists have utilized state-of-the-art research on snowflake physics to determine the likely density of snowflake water content as snow accumulates on the ground. The model factors in temperatures within the clouds as well as the atmospheric conditions that the flakes encounter as they fall to the ground.
